Further features with option U02
Option U02 is a firmware upgrade that increases the capabilities of the
PSA3605 or PSA6005 to include the following features (marked with *).
Triggered sweep*
The standard sweep modes of continuous repeat and single shot can be
extended to include triggered sweeps from an external signal or internal
limits comparison.
Limit patterns and limits comparator*
Limit lines and patterns can
be defined which can be
simply visual aids or create
automatic actions. Zone
restriction can be applied.
A single or dual line limits
comparator can be used to
generate audible warnings,
output signals, or to freeze
or log the trace.
Channel Markers *
Channel Marker List files are a special type of limit pattern file that
contain only vertical lines. They can be particularly useful for showing
channel position frequencies.
PSA-Manager provides
an editor that enables
them to be created by
simply entering a list of
frequencies. Each file can
contain up to 50 marker
lines.
Offsets and Compensation Tables*
The reference level, graticule and marker readouts can be set to
compensate for external attenuation or gain to a resolution of 0.1dB.
Compensation can also
be added for signals
emanating from a 75W
source.
Tables can be loaded that
compensate for variations
of level with frequency for
specific antennae or transducers. The tables can contain up to 100 points
and are linearly interpolated between points.
Custom Presets *
Custom Presets is an extended version of the User Preset from which
multiple presets can be saved or recalled by entering just a number.
Applications for which Custom Presets might be used include frequency
selection via channel numbers, or repetitive steps within a test
environment.
Data Logging*
The PSA Series II can log results in response to a variety of stimuli. Data
is stored as files that can be transferred to a PC for analysis using PSA-
Manager software.
The data stored can be the
peak level, centre frequency
level, the whole trace, or
a bitmap screen image.
Each file can contain up to
25,000 entries.
The 1.8GB of internal memory enables vast amounts of data to be stored.
Logging entries can be created by an internal timer (adjustable from
seconds up to hours), the manual trigger key, the external trigger input,
or the limits comparator.
Automatic Measurements*
Automatic measurements
of Channel Power (CP),
Adjacent Channel Power
Ratio (ACR) and Occupied
Bandwidth (OBW) can be
performed.
Measurements can be
performed continuously or
in single-shot mode.
Waveform Demodulation*
In addition to audio
demodulation of AM or FM
signals, the modulating
waveform can be displayed
against a timebase settable
between 5us/div and
20ms/div.
Markers can be used to
measures modulating
frequencies and depth or
deviation.
View on PC*
View on PC enables the screen of the spectrum analyzer to be sent to a
PC by USB. The screen image can be set to a user definable size and is
particularly useful for education and training purposes.
